Si Liu has joined the high performance computing group at TACC as a Research Associate since 2013. He is conducting research on HPC software tools and providing the science and engineering community with superior user experience. He is also collaborating with academic and industrial institutions all over the world on various data-intensive research projects that demand advanced HPC technology and cyberinfrastructure, including realizing high-resolution WRF simulations, improving the parallel IO performance of HDF5 and OpenFOAM, and setting up computing environment for a large data analysis effort of CERN's ALICE experiment.
During 2009-2013, Si worked as a software engineer in Computational Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR). He participated in establishing the Yellowstone supercomputer system in the NCAR-Wyoming Supercomputing Center (NWSC) for climate research, provided consulting services and technical support to scientific computing communities, and collaborated with scientists on climate models development and optimization.
